Install Dot net 3.5 offline

Dism /online /enable-feature /featurename:NetFx3 /Source:X:\sources\sxs /all /LimitAccess

You can try:

  1. Delete everything under: C:\Windows\SoftwareDistribution\Download
    Those are left over from Windows Updates and no longer needed.
  2. From Admin Command prompt, run:
    Dism /Online /Cleanup-Image /StartComponentCleanup
  3. Turn on Net Framework 3.5 from programs & Features again to see if it helps.


choco install dotnet3.5

Reinstalling grub on an unbootable Debian system


Fixing an unbootable computer after a failed grub installation can be a bit tricky. Here’s what I ended up doing.

First of all, boot the machine up and get access to the root partition:

  1. Get a Debian installation CD for the same architecture (i.e. don’t use an i386 CD if your root partition is amd64). The distro version doesn’t matter too much: a lenny CD will boot squeeze/sid just fine.
  2. Boot the install CD and select Rescue mode under Advanced options.
  3. Answer the language, keyboard and network questions any way you want and provide the decryption passphrases for any of the encrypted partitions you need to mount.
  4. When prompted, request a shell on the root partition.

If you need to upgrade the version of the grub package (for example if this problem was caused by a bug which is now fixed):

  1. Make sure that the network interface is up (ifup eth0).
  2. Make sure that /etc/resolv.conf has at least one nameserver line, otherwise add one.
  3. Install the latest version using apt-get or dpkg.

Now that you have the right grub version, run the following (with the right device name for your machine):

grub-install /dev/sda  

Finally, reboot and cross your fingers



All your documents and settings will be restored to the exact same state they were in when the last snapshot was taken. Redo Backup and Recoveryis a live CD, so it does not matter if you use Windows or Linux. You can use the same tool to backup and restore every machine. And because it is open source released under the GPL, it is completely free for personal and commercial use.


More Features, Less Complex

Redo Backup has the most features coupled with the simplest, most user-friendly interface:

  • Easy graphical user interface boots from CD in less than a minute
  • No installation needed; runs from a CD-ROM or a USB stick
  • Saves and restores Windows and Linux machines
  • Automatically finds local network shares
  • Access your files even if you can’t log in
  • Recover deleted pictures, documents, and other files
  • Internet access with a full-featured browser to download drivers
  • Live CD download size is only about 250MB

With an incredibly simple user interface and the ability to encrypt and backup your data to network drives, external drives, FTP/SSH servers and even Amazon S3 storage, Déjà Dup is the perfect Linux backup solution. Set up a secure, regularly-scheduled backup in minutes. It’s like Carbonite for Linux, except you can pick where your data goes.

Linux backup software is certainly nothing new. Many people swear by rsync for their backup needs, while others like Back In Time, an easy backup program for Linux.

Cloud Design Patterns: Prescriptive Architecture Guidance for Cloud Applications


MSDN Cloud Design Patterns

The patterns & practices team at Microsoft has collected twenty-four design patterns that are relevant when designing the architecture of a cloud application.  Each pattern includes a brief discussion of the benefits, considerations and implementation of each pattern.  The collection of patterns is not meant to be comprehensive and is instead focused on the most popular design patterns for cloud applications.

The guide consists of a collection of web pages each individually focused on a pattern.  The pages are broken down into sections describing the problem domain, a high-level technical solution, how this patterns solves the problem, considerations when using the pattern, an example implementing the pattern and when the pattern is suitable. The patterns included in this guide can be used in many ways including:

  • Implement the sample code as a starting point for your own cloud application
  • Use the Context, Problem and Solution sections of a pattern’s web page as discussion points during an architectural design session
  • Use the Example section of a pattern’s web page to teach colleagues about a design pattern
  • Use the Issues and Considerations section of a pattern’s web page to identify common issues in your problem space

The remainder of this module will focus on a subset of patterns from the Cloud Design Patterns documentation and explain why they are important to understand and how they relate to the decisions you will make as an Azure architect.



Fix win 10 folder ACL


cd /users/xxx

icacls Pictures /reset /t /q (this will reset all the permissions on Pictures folder tree to default)

cd /<onedrive folder> (i.e. cd to base OneDrive folder)

icacls Pictures /reset /t /q


Press Windows key + R and type control userpasswords2 and click OK Select the user name and click Properties Click on Group Membership Make sure Administrator option is selected Also, click the option Other and select Administrator from dropdown Click Apply and then OK Restart the computer and check

If the issue still persists, enable the hidden Admin account and check. Press Windows key + X and click Command Prompt (Admin) Type the following command and press Enter net user Administrator /active:yes To exit Command Prompt, type Exit and press Enter or simple click X on top right of the same window.



To reset files permissions, follow these easy 3 steps:

Step 1: Run “cmd” as Administrator.

Note: In MS Windows 8 and above, press the Win+X keys, then choose “Command Prompt (Admin)”.

Step 2: Go to the drive or folder in question, for example:

CD /D D:

Step 3: To reset all the files permissions, type:

icacls * /T /Q /C /RESET


Very Important note:

Step 3 is irreversible. Make sure you backup the permissions before you proceed!

It is possible that “icacls” might fail. For that try to take ownership of the files first. Just before Step (3), please type the following command:

takeown /R /F *


You will need to run ‘Subinacl Tool’ to reset the permission to normal. To reset system permissions, follow the steps:

1.       Download subinacl.msi from the following link, and save it on the desktop.
http://www.microsoft.com/downloads/details.aspx?FamilyID=e8ba3e56-d8fe-4a91-93cf-ed6985e3927b&displaylang=en#AffinityDownloads (http://www.microsoft.com/downloads/details.aspx?FamilyID=e8ba3e56-d8fe-4a91-93cf-ed6985e3927b&displaylang=en#AffinityDownloads)
2.       On the desktop, double-click subinacl.msi to install the tool.
3.       Select C:\Windows\System32 as the destination folder.
Note This step assumes that Windows is installed in C:\Windows. If Windows is installed elsewhere, select the appropriate path to .\System32.
4.       Open Notepad.
5.       Copy the following commands and then paste them into the opened Notepad window.

subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f
subinacl /subkeyreg HKEY_CURRENT_USER /grant=administrators=f
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=administrators=f
subinacl /subdirectories %SystemDrive% /grant=administrators=f
subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=system=f
subinacl /subkeyreg HKEY_CURRENT_USER /grant=system=f
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=system=f
subinacl /subdirectories %SystemDrive% /grant=system=f

6.       In Notepad click FileSave As, and then type: reset.cmd
7.       In Notepad click Save as type, and then select All Files (*.*).
8.       Save the reset.cmdfile to your desktop, and close Notepad.
9.       Double-click the reset.cmdfile to reset the Windows Update permissions.
Note This step may take several minutes, so please be patient. When the permissions have been reset, you will be prompted with “Finished, press any key to continue.”
10.    Press any key to complete the installation.


Check if you have the right permissions to all the folders for all users.
